Nepenthes pervillei wont tolerate high light

[leck7S]

Its the weirdest thing, given how pervillei is one of those species that grow completely exposed to full sun.
However I've had this plant for about 8 months now and every time I tried to increase the light intensity just a notch it starts getting blush and sometimes splotches on it leaves, so what gives?
Currently the conditions are 230PPFD and 11 DLI

Whats the humidity and airflow like? Its habitat is very sunny but also very windy. If you dont have a lot of air circulation its possible it'll be showing light stress when it normally wouldn't.

I've never tried growing this species but I found this Nepenthes pervillei growing guide. Hope it helps.
